I've grown curious to try out one of these aftermarket buffer springs that I see several praise. I'm currently deciding between the Tubb spring and the Sprinco Blue spring. Any personal experiences with either of these? Anyone tried both of them?

I only ask because I now have the Sprinco Red Spring(heavier than blue). I got it for my 16" carbine, which is over gassed and ejects at about 2-3 o'clock, thinking it might change where the spent casings landed. It made no difference at all. It still ejects at the same location and recoil feels the same. Now, I shouldn't have to change the spring for some time due to their life cycle, but it didn't change anything. I also got the 5 coil extractor spring it that matters at all. They are both more or less upgrades but didn't change the way the rifle functions. Just reliability upgrades.

FWIW, I already had a full auto BCG and ST-T2 buffer in the rifle before I tried the Sprinco upgrades.

I just spent awhile speaking on the phone to one of the guys at Sprinco and he's saying their blue spring with an H2 buffer will be the best combo in my 14.5" and 16" middies. And that their white spring with an H2 buffer will be the best combo in my 11.5" carbine.

He was inquiring about who was the barrel manufacturer and such for each rifle. I may have to take his word for it and go the Sprinco route.

I have two Colt 14.5 SOCOM barreled carbines. Both have Sprinco blue springs and H2 buffers. The gas ports are .063
No malfs with either carbine and between the two have over 6000 rounds of M193, M855 and MK318 Mod O. 5000+ on one and 1000 on the other
